About “A child process exited abnormally with code -1”

[lihanwei007]

After running the model in SyncroSim, I got the warning message like this and I have no idea how to solve it：

[Failure] A child process exited abnormally with code -1
D:\LUCC\LUCAS\work4\620\ST-Sim State-and-Transition Simulation Model.ssim.temp\Parallel\Scenario-6\Job-1.ssim More information:
Exception of type ‘System.OutOfMemoryException’ was thrown.

Any one can do me a fever?

Hi Hanwei,

This System.OutOfMemoryException usually means that there is not enough RAM on your computer to handle the memory required for the simulation. You need to either reduce the number of jobs you are running or run this simulation on a computer with more memory.

Hi Leonardo,

Thank you, I will run it on other computer.

Hi Leonardo,

One more question, could I run the simulation on the cluster?

Thanks for your time.

Hi Hanwei,

The short answer to your question is yes, ST-Sim can be run on a cluster and has been done so by others. Most recently this study: https://onlinelibrary.wiley.com/doi/abs/10.1111/gcb.14677

The long answer is that this is a fairly complicated process that will require you to run on linux and use the syncrosim command line and/or rsyncrosim package.

Regards,
Leonardo
